Article 6 — SAFETY MEASURES.

Lights shall be installed and used during nighttime drilling on each and every derrick and at other times whenever necessary for adequate lighting.

Whenever it shall be necessary, in order to protect any property or persons thereon, the Director of Public Works may order and require that any derrick erected be sufficiently enclosed with galvanized iron or other suitable substitute so as to prevent the escape onto public or private property, or persons thereon, of any oil, gas, mud, water, steam or other gases, fluids or substances from said well, and the licensee for such well shall, within twenty-four (24) hours after service upon him of notice of such order of said Director of Public Works, make or cause to be made, such enclosure.

The outlets from every exhaust of any engine or boiler used in connection with any oil well, well hole, derrick, or production equipment, shall be connected to an exhaust and muffler box of approved type or design, to prevent the emission or escape of sound, sparks or ignited carbon or soot. Said box shall be located not less than twenty (20) feet from any street, road, alley or thoroughfare, dedicated to or in use by the public. Undue noise from such exhaust is hereby prohibited.

a) The smoke stack of every boiler used in connection with any oil well, well hole, derrick or production equipment, shall be equipped with a screen or other device of approved type or design, to prevent the escape from such smoke stack of sparks or ignited carbon or soot; providing, however, that when the top of any such smoke stack is at least thirty (30) feet above the ground level, such screen and other device may be omitted.

b) No person shall install, maintain or operate any steam boiler within twenty-five (25) feet of the center of the well hole of any oil derrick or any tank containing gas or flammable liquid.

c) If more than one (1) steam boiler is to be hereafter erected, maintained or operated for a particular use, such steam boiler or battery of boilers, except when housed or enclosed, or except when burners are elevated to a height of twenty-four (24) inches above the surrounding terrain, shall by completely surrounded by a dike not less than twenty-four (24) inches in height, constructed as provided hereinafter for tanks, located not less than fifteen (15) feet distant from such boiler or battery of boilers.

a) On or after August 1, 1959, no person shall dig or cause to be dug, any sump on any oil well site or at any other place in connection with the operation of any oil well.

b) On or after January 1, 1960, no person shall own or operate, or have possession of, or be in control of any oil well site on which a sump is located, or any sump used in connection with the operation of any oil well; provided, however, that the provisions of this subsection shall not apply to portable sumps required by the State Division of Oil and Gas or by the Regional Water Pollution Control Board.

c) On or after January 1, 1960, no person shall own or operate, or have possession of, or be in control of any oil well site on which a sump has been located, or of any property on which has been located a sump used in connection with the operation of any oil well, unless such sump has been drained and filled with earth to the level of the surrounding terrain.

(Added by O-2709)

a) It shall be unlawful to decorate any oil well pump or other moving part of any item of equipment enclosed or required to be enclosed within an oil well site with any display or representation which constitutes an attractive nuisance to children.

b) If the City Manager determines that an attractive nuisance exists as set out in subsection a) hereof, he may order it to be abated or removed, or may take any other steps which he deems necessary to remedy the condition.

c) In determining whether an attractive nuisance exists, the City Manager shall consider the following factors and such other as he may deem relevant:

1. Whether the place where the condition exists is one where the possessor of the property knows or has reason to know that children are likely to trespass.

2. Whether the condition is one which the possessor knows exists or has reason to know exists and realizes or should realize will involve an unreasonable risk of death or serious bodily harm to such children.

3. That children of sufficient age or mental capacity to be allowed at large would not discover the condition or realize the risk of intermeddling with it or in coming within the area made dangerous by it.

• 4. The utility to the possessor of maintaining the condition and the burden of eliminating it are slight as compared to the risk to children involved.
• 5. The possessor has failed to exercise reasonable care to eliminate the danger or otherwise protect children.

(Added by O-3227)

Except as provided in Section 97.6.11, prior to the issuance of any grading or building permit for the development of any lot or parcel of land where a previously abandoned oil or gas well exists, the person seeking the said permit or permits shall prove to the reasonable satisfaction of the Director of Building and Safety that any such well or wells have been abandoned to the most current abandonment standards required by the California Division of Oil and Gas.

(Added by O-3227)

Where any structure is to be constructed or placed over an oil or gas well abandoned pursuant to the provisions of Section 97.6.9, the well or wells shall be fitted with a gas venting system approved by the California Division of Oil and Gas.

Said gas venting system shall be installed in such a manner and location as to permit convenient testing for the presence of gas.

(Added by O-3227)

In the event any person seeking a grading or building permit for a lot or parcel of land where a previously abandoned oil or gas well or wells exist, and the person seeking the permit or permits presents to the Director of Building and Safety a written waiver of the requirements in Section 97.6.9 from the California Division of Oil and Gas, the placement of any building or structure on the lot or parcel and the size and shape of the said lot or parcel shall be such that future re-abandonment of the well or wells will be possible.

In order to so permit future re-abandonment, an open and unobstructed area shall be provided immediately adjacent to the surface location of the well head as follows:

a) No structure or property line shall be closer than ten (10) feet to any two (2) adjacent sides of the said well; and

b) No structure or property line shall be closer than fifty (50) feet from the third (3rd) side of the said well; and

c) The fourth (4th) side shall have open access so that an oil well abandonment rig can be driven onto the site.
